Replace custom button component with QQC2 buttons

Now that we've moved qtquickcontrols2 into the qtdeclarative submodule.
We want our examples to simply use qqc2 controls, rather than custom
made buttons and other controls.

This example used a custom made button component, which this patch will
replace with qqc2.

It will also use qqc2 in other places where it makes sense, like replacing
a TextEdit with a qqc2 TextArea, and Text components with qqc2 Labels.

Task-number: QTBUG-95733
Pick-to: 6.2
Change-Id: Ic733cd592cd10ef2cf45058aaf08a0f6b2f5bd2c
